Abstract
In laboratory studies conducted at Stoneville and State College, Mississippi, 5 environmental stimuli induced diapause in the boll weevil, Anthonomus grandis Boheman: (1) exposure to an 11-hour photoperiod in the larval and pupal stages; (2) exposure to night temperatures of 10 in the adult stage; (3) boll feeding in the adult stage; (4) limitation of the quantity of squares fed in the adult stage; and (5) boll feeding in the larval stage. Wild strains of weevil in Mississippi responded to these stimuli, but the State College laboratory strain did not.This publication has 7 references indexed in Scilit:
